For GCRG Only

GCRG awarded NSF grant towards the annual budget of CH4 emissions from tundra ecosystem across a latitudinal gradient

GCRG was awarded a grant by the US National Science Foundation for the proposal, “Methane loss from the Arctic: towards an annual budget of CH4 emissions from tundra ecosystem across a latitudinal gradient” (PI: Donatella Zona). In this research project we will measure CO2 and CH4 fluxes across a latitudinal transect in the arctic tundra continuously for two years. We will also compare two different methods of determine winter CO2 effluxes (eddy covariance and soil respiration gradient). The dataset provided by this research will make a fundamental contribution toward reducing uncertainties of the terrestrial contribution of arctic ecosystems to total GHG emissions, and ultimately help reduce large uncertainties in model predictions following climate change.
